Opioid Consumption, PostoperativePhase 3NCT07654296
Assessing Suzetrigine for Pain Reduction Following Ureteroscopic Surgery
A Phase 3 study testing multimodal analgesia regimen without suzetrigine and Suzetrigine in people with Opioid Consumption, Postoperative and Multimodal Analgesia, run by Brigham and Women's Hospital at 2 sites in United States.
Trial summary
Urologic surgery has advanced with new technologies to allow less invasive management of common afflictions such as kidney stones, these procedures are notoriously painful as the ureter must be dilated to accommodate any instruments, and a ureteral stent is often left following surgery to allow for adequate healing.

About this study
Official title: Multimodal Analgesia Pathway Assessing Role of Suzetrigine for the Reduction of Opioid Use Following Ureteroscopic Surgery
Urologic surgery has advanced with new technologies to allow less invasive management of common afflictions such as kidney stones, these procedures are notoriously painful as the ureter must be dilated to accommodate any instruments, and a ureteral stent is often left following surgery to allow for adequate healing. Unfortunately, stents are poorly tolerated by a significant number of patients, with up to 100% complaining of bothersome pain and 10% of patients with unplanned healthcare visits. Further complicating kidney stone management is the frequency of concurrent chronic kidney disease (CKD) or acute kidney injury (AKI) that prohibits many patients from taking NSAIDs which limits pain management options. There is now a push to treat these patients with multimodal analgesia to provide better care and reduce opioid use. Suzetrigine is a new a first-in-class selective inhibitor of the NaV1.8 sodium channel that functions as a non-opioid analgesic developed to treat acute pain and neuropathic pain. This study assesses the addition of suzetrigine to standard-of-care multimodal analgesia. We hypothesize a demonstrated decrease in opioid use, decrease Emergency Room visits within 30 days, decrease the number of unplanned care encounters.

We hypothesize a demonstrated decrease in opioid use, decrease Emergency Room visits within 30 days, decrease the number of unplanned care encounters. This prospective open-label interventional single-center study will compare 30-day postoperative patient reported outcomes and pain medication use between a pre-implementation cohort of patients managed with standard-of-care multimodal analgesia after ureteroscopy with a post-implementation cohort of patient with this regimen and addition of suzetrigine. The primary outcome will be opioid usage after discharge with standard of care multimodal analgesia (historical control) vs opioid usage after discharge with suzetrigine included with the standard of care
multimodal analgesia regimen (intervention). Secondary outcomes will include unplanned care encounters within 30 days (Emergency Room, unplanned clinic visits) and surveyed patient reported outcomes measured on a post-operative survey including PROMIS (Patient-Reported Outcomes Measurement Information System) questions as well as an end of study administration of WISQOL (The Wisconsin Stone Quality of Life Questionnaire). The study will be conducted within a single academic institution including the primary hospital (Brigham and Women's Hospital) and satellite sites (Brigham and Women's Faulkner Hospital).

The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

Unfortunately, stents are poorly tolerated by a significant number of patients, with up to 100% complaining of bothersome pain and 10% of patients with unplanned healthcare visits. Further complicating kidney stone management is the frequency of concurrent chronic kidney disease (CKD) or acute kidney injury (AKI) that prohibits many patients from taking NSAIDs which limits pain management options.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing multimodal analgesia regimen without suzetrigine and Suzetrigine in people with Opioid Consumption, Postoperative and Multimodal Analgesia, run by Brigham and Women's Hospital at 2 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 18 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Daniel A Wollin, MD, MS (617 732 6354, dwollin@mgb.org), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Post-discharge opioid consumption (MME) (time frame: 1-2 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Sep 2026; AzTrials last refreshed its copy on 7 Nov 2026.
